The key is to think of agents the way you would think of a software team: specialization helps, but only if there's a clear contract for how they communicate. Most failures happen because every agent can edit everything.
A common pattern is a supervisor + specialists architecture:
User
│
Supervisor Agent
/ | \
/ | \
UI Agent Backend Agent Test Agent
\ | /
\ | /
Integration / Review
│
Final Output
The supervisor never tries to do all the work itself. Instead it:
- Breaks the request into tasks.
- Decides which agent owns each task.
- Collects outputs.
- Resolves conflicts.
- Produces the final result.
Each specialist has a narrow responsibility.
UI agent
- React/Vue/Swift/etc.
- Accessibility
- UX consistency
- Component structure
- Design system
Shouldn't rewrite backend APIs.
Backend agent
- Business logic
- Database
- API design
- Performance
- Authentication
Shouldn't redesign the interface.
Testing agent
- Unit tests
- Integration tests
- Edge cases
- Regression analysis
- Static analysis
Shouldn't invent new features.
That separation dramatically reduces conflicts.
Give each agent ownership
Instead of:
"Everyone can modify everything."
Use ownership like:
UI
owns:
/frontend
components
styling
Backend
owns:
/server
database
API
Testing
owns:
tests
CI
If another agent needs a change outside its area, it requests it instead of making the edit.
Pass structured context
Instead of giving every agent the full conversation, pass only what's relevant.
Example:
Task:
Implement profile page.
Shared context:
- API already exists
- Auth required
UI Agent receives:
- component tree
- design tokens
- endpoint spec
Backend Agent receives:
- endpoint requirements
- DB schema
Testing Agent receives:
- acceptance criteria
Less context generally leads to fewer hallucinations and more focused work.
Communicate through artifacts
Avoid free-form conversations between agents.
Instead exchange structured outputs like:
{
"task": "Create profile endpoint",
"status": "complete",
"files_changed": [
"routes/profile.ts"
],
"public_interface": {
"GET /profile": {
"returns": "Profile"
}
},
"notes": [
"Requires authentication"
]
}
Artifacts are much easier for another agent to consume than paragraphs of explanation.
Add review agents
Many teams use another layer:
Supervisor
│
┌────────┴────────┐
│ │
Specialists Reviewer
The reviewer checks:
- coding standards
- architecture
- security
- consistency
- style
without rewriting everything.
Resolve conflicts centrally
Don't let agents argue indefinitely.
Instead:
- UI proposes change.
- Backend proposes API.
- Supervisor notices mismatch.
- Supervisor requests revisions.
- Final merge.
Only one agent should decide the final state.
Work in phases
Rather than letting all agents edit simultaneously:
Planning
↓
Backend
↓
UI
↓
Testing
↓
Review
Or, if tasks are independent:
Plan
↓
UI ─────┐
Backend ├── Merge
Tests ──┘
The important part is synchronization before merging.
Keep a shared source of truth
Every agent should read the same project specification.
For example:
Requirements.md
- Feature goals
- Constraints
- API contracts
- Naming conventions
- Acceptance criteria
Without this, agents tend to drift toward different assumptions.
Limit autonomy
A useful pattern is to define what each agent can do without approval.
For example:
UI
✓ create components
✓ adjust CSS
✗ change API
Backend
✓ add endpoints
✓ migrations
✗ redesign UX
Testing
✓ write tests
✓ report failures
✗ change production code
This prevents one agent from unexpectedly changing another's work.
A practical workflow
For a request like "Add user profiles":
- Supervisor creates a work plan and identifies dependencies.
- Backend agent implements the database schema and API.
- UI agent builds the profile screens against the agreed API.
- Testing agent writes unit, integration, and end-to-end tests based on the acceptance criteria.
- Reviewer agent checks consistency, security, and coding standards.
- Supervisor verifies that the implementation meets the original request before presenting the result.
The overarching principle is to minimize overlap, maximize explicit contracts. Agents work best when they communicate through well-defined artifacts (plans, API contracts, and test reports), have clear ownership boundaries, and rely on a coordinator to manage dependencies and resolve conflicts, rather than negotiating changes directly with one another.
